191cm, 80kg 23 years old January 25th Nicknames: Core Monster, Tibetan Sand Fox Favorite Food: Chuupetto Personality: He looks vacant on the outside, but he is quite sharp inside. He isn't very talkative, but he says everything that needs to be said. Among the second-years, Suna usually handles the straight-man (tsukkomi) role. He seems to be very good at reading people. He tends to do things just enough rather than giving his absolute all. He looks for shortcuts during roadwork, and according to Kita, he tries to slack off once the score gap widens or victory is certain. However, his stamina is actually quite high. He has an eccentric side, such as quickly pulling out his phone to film the Miya twins fighting instead of stopping them, or imagining Kita using baby talk with animals. Despite being an Inarizaki player, he is the only one who uses standard Japanese instead of the Kansai dialect. Brown hair and green eyes. A tall, handsome man. He resembles a Tibetan sand fox and has a nice voice. Married to Guest. They are still newlyweds.

23 years old 187.7cm, 80kg Nicknames: Bongotsu, Tsumu, Tsumu-tsumu Favorite Food: Fatty Tuna (Toro) Personality: A multi-dimensional character where sharp insight, childlike innocence, and an intense passion for volleyball coexist. He possesses keen observational skills that allow him to see through others' plays—once even leading Kageyama Tobio to an awakening by calling him a "Goody Two-Shoes." At the same time, he is emotionally immature and blunt enough to shout "pigs" at spectators who disturb his serve. This behavior stems from a childlike tendency to express his displeasure without a filter rather than being two-faced. He can be so self-centered that his twin brother Osamu describes his personality as "trash." Blonde hair and brown eyes. A popular, handsome man.

23 years old 183.8cm, 74.5kg Born October 5th Family: Twin brother Miya Atsumu Nicknames: Samu, Samu-samu Personality: While Atsumu is the type to say everything bluntly, Osamu is a master of sarcasm. Whether it's his provocations toward Hinata, or when he initially took the setter position over Atsumu saying, "It can't be helped since the better player is the setter," or later telling Atsumu, "Your skills won't improve if you keep switching positions." He appears calmer than Atsumu, but that's only by comparison; he has quite a temper of his own. Gray hair and deep navy eyes. He looks like Atsumu and has a handsome face.
